CAR-COUPLING.

To all whom it may come/11.:

Be i t known that I, ()RLANDO LEE Amman song. a citizen of the United States. and a resident of Richmond, in the county of lienrico and State of VirginiaQhave invented certain new and useful improvements in Car-Couplings. of which the following is a specification.

This invention is an improvement in car couplings of the twin-jaw type: and the invention consists in certain novel constructions and combinations o'l parts asiwill he hereinait er described and claimed.

in the drawing Figure 1 a perspective view of thc in\"enti m. l ig. is a detailed perspective view of the lever tor opening the pivoted jaw or knuckle. Fig. 3 is a detail perspective view showing the pivoted jaw or knuckle, the coupling pin, and the lever for opening the jaw in the position such parts occupy when the jaw is closed. Fig. l a similar view of the same parts in the position they oecppy when the jaw partially opened. Fig. 5 is a vertical longitudinal section of the coupling on about line ?--5 of Fig. (3. Fig. (3 is a horizontal section of the coupling with the parts in the position they occupy when the jaw is closed. and Fig. 7 is a similar view showing the pivoted jaw or kiuickle open.

The couplingcomprises the draw-head A having the fixed jaw 13 and the pivoted jaw or knuckle (l, which latter is pivoted at grooved or recessed along its rear face at.- its upper edge at to torn'i a bearing for the lug E de' pending from the mvixrg ine front end of the arm E of the jaw-(melting lever I presently described. The shank C also has at its swinging end an inclined surface at (3 which rides below a shoulder on the coupling pin.

The draw-head A has a bottom wall A and atop wall A", and the latter is pro vidcd alongside the pin-opening, A with an upwardly projecting; chamber A, which coniimunicates atits lower end with the interior of the draw-head and receives the up wardly projecting, pivot portion E of the lever E. This pivot portion, itwil]. be noticed projects upwardly above the arm E which. latter operates directly below thcztop wall A of the draw-head, and the pivot portion E is rounded on its front face at to bear against the front. wall of the Specification of Letters Patent. Application filed November 18, 1907.

chamber A, and the lever is pivotally held on a bolt F extending upwardly through the pivot portion E and thence up through I the top wall of the chamber A and suitably secured. The opening lever E is also provided with a short arm E projecting toward the coupling pin G, and having at its extremity a projecting reduced portion E, which operates in a recess G in the side of the coupling pin G above the shoulder G ml: which is engaged by the inclined portion C- of the knuckle C. This recessG has at its lower end an inclined surface or cam G which engages with the lever arm E when the pin G is raised to its uppermost posit-ion, and adjusts the lever E from the position shown in Fig. 6, to that shown in Fig; '7, so f I of the. lever will throw the pivoted jaw or knuckle to open position. The recess G also has an upper inclined surface G located directly above the cam G? and engaging with the arm E of the lever E, when the parts are in the, position shown in Figs. 3 and 6, thus positively readjusting the lever E to the position shown'in Fig. 6, against the wall of-the draw-head. The cam surface G is so arranged rela-- tively to the arm E of the lever E, that it will not operate upon said 'arni until after the pin G has'reached a position in which it releases the knuckle C so that in operation, as the pin G is lifted, the said pin will first release the pivoted jaw or knuckle and will. then on its further movement operate on the arm E of "the lever E to positively throw the knuckle to open position. It will also he noticed that it' at any time the knuckle (3- should be released and partially opened, the pin G may be lifted to operate upon the lever E to throw the knuckle C to its full that the arm E I propose to employ any suitable means for raising the pin G: but, in this instance, I show for this purpose, a rock shaft H supported in brackets L secured to the front of a car body, and the inner end of said shaft is provided with a forwardlyextending arm which projects beneath, and is thus adapted to engage, a hook G with which the head of the pin is provided.

It is apparent that, by rotating the shaft H by means of a handle provided at its outer end, the pin may-be raised as required. 1

At its forward swinging end the arm E of the lever E is provided with :1 depending C of the 1' within therecess C lug E, which operates in rear of the shank knuckle C, and within the recess C thereof, see Fig. 4, in actuating the knuckle C from its closed position, as shown in Figs. 3 and .6, to its open position, as shown in Fig. 7, Fig. 4 showing the knuckle C partially opened.

When the knuckle C is closed in Figs. 3 and 6, the depending l as shown g lies of the lever extending above the shank G and within a recess C so that the jaw when closed does not exert any pressure whatever against the jaw-opening lever, but bears enupwardly projecting pivot portion extend ing within the upwardly projecting chambet of the draw-head, and having a forwardly projecting arm operating above the shank of the jaw and provided at its swinging end with a depending lug operating in the recess in said shank, the said opening, lever having a second arm projecting laterally from its pivotlportion, and a coupling pin having in its side facing said second arm of the opening lever a recess whose lower wall is inclined forming a cam surface for the body of the arm E engagement by said arm of the opening 1ever, said coupling pin secure and release the shank of the pivoted jaw, all substantiallyas and for the purpose set forth.

2. The combination of a draw-head, a pivoted jaw having a shank, a jaw-opening lever pivoted in the draw-head and having a forwardly projecting arm for operating the jaw shank and also having an arm eX- tending laterally to its pivot, and a coupling pin arranged laterally to the pivot of the jaw-opening lever and h g in its s d facing said pivot of the lever, a recess receiving the end Of the laterally p j g arm of the opening lever and having aid recess provided with a lower inclined Well. forming a cam surface operating upon said lateral arm of the opening lever to actuate the same to open the jaw, and having the upper caln wall to operate upon Said'leteral arm of the opening lever whereby to re-adjust the latter, substantially as set forth.

3. Acar coupling substantially as described comprising a. draw-head, a pivoted jaw having a shank, a pivoted jaw opening lever having a forwardly projecting arm engaging with the jaw shank to open said and also having a second arm projecting laterally to its ,ivot and a coupling pin having in its side faeinp. the end of said second arm a recess receiving said end and having a lower inclined wall forming L cam Surface to engage the said end of the second arm operate the lever, substantially as described.
